Composite reinforcing bars (rebars) that are used in concrete members with high performance (strength and durability) properties could have beneficial effects on the behavior of these members. This is especially vital when a building is constructed in an aggressive environment, for instance a corrosive environment. Although tension capacity/weight (or volume) ratios in composite rebars (carbon ...

Due to the widespread applications of fiber reinforced polymer composites in various industries, the machining of these materials to reach the desired shapes, close tolerances and surface finish quality is of great importance. But the composite materials are anisotropic and are mostly prepared in laminated form and, therefore, they have special chip formation behaviour. Among the effective para...

This paper presents an experimental study on the tensile behavior of basalt-fiber-grid-reinforced mortar (BGRM) before and after exposure to elevated temperature 300 °C considering effect fiber grid type, short polyvinyl alcohol (PVA), high-temperature time. The results show that plates reinforced with woven textile T25 fiber-reinforced polymer (FRP) G50 exhibited more pronounced strain-hardeni...

Bu çalışmada klasik autoklav yönteminden farklı olarak sıcak pres ile prepregten kompozit malzeme üretilebilirliği üzerinde çalışılmış ve elde edilen polimer matrisli kompozitlerin darbe davranışları incelenmiştir. Bunun için 3mm kalınlığında 90 mm çapında aramit takviyeli malzemeler yöntemi üretilmiştir. Darbe davranışı karekterizasyonu içim 15, 30, 45J enerjiye sahip düşük hızlı testleri gerç...

Externally bonded carbon fiber reinforced polymer (CFRP) laminates are a feasible and economical alternative to traditional methods for strengthening and stiffening deficient reinforced concrete and prestressed concrete girders as shown in Fig. (1). Although extensive research has already been undertaken to investigate the behavior of CFRP strengthened bridge girders, the majority of work condu...

Research on increasing the buckling strength of tanks carrying fluid and also cylindrical shells of thin-walled steel in civil engineering and mechanics is important. This is due to the widespread use of these structures in the industry. Due to the low thickness of the body and also due to the pressure forces entering these tanks, these structures are exposed to lateral buckling. In this resear...
